SARS-CoV-2 is an enveloped virus. Proteins of the lipid based envelope are not rigidly arranged as compared to non-enveloped viruses lacking lipid based outer layer. Rigidly arranged multivalent display has been reported to be important for potent immune stimulation.

This phenomenon, observed following brain injury or neurodegeneration, is postulated to contribute to neuronal repair and functional recovery, thereby presenting an avenue for endogenous neuronal restoration. This study investigated the extent of regenerative response in hippocampal neurogenesis by leveraging the well-established kainic acid-induced status epilepticus model in vivo.

Recent research studies show correlation between blood and cerebrospinal fluid (CSF) levels of BACE1 with the pathophysiology of AD. In this study, we report one-step synthesized reduced graphene oxide (rGO), activated carbodiimide chemistry, conjugated with BACE1 antibody (Ab), and immobilized on fluorine-doped tin oxide (FTO) electrodes for rapid detection of BACE1 antigen (Ag) for AD diagnosis.

Although lungs are considered as the primary infected organs by SARS-CoV-2, some of the other organs, including the brain, have also been found to be affected. Here, we have discussed how SARS-CoV-2 might infect the brain.

These conditions get changed quite often, and often involve changes introduced into the gut microbiota which, as studies are revealing, directly modulate the CNS via a crosstalk. This cross-talk between the gut microbiota and CNS, i.

Last year, the human hippocampal neurogenesis field was flipped on its head by a paper in Nature from Sorrells et al. questioning the presence of human hippocampal neurogenesis during adulthood ( Sorrells, S.
